When changing the standard the saa6752hs was not updated unless the input was the TV tuner. The saa6752hs should be updated regardless of the input. In addition the S_STD and G_STD ioctls for the mpeg video device didn't do anything. This is now fixed: they behave just like S_STD and G_STD on the video0 device. Signed-off-by:

cx18: Increment u8 pointers not void pointers. Incrementing void pointers is dubious and the real intent in cx18_memcpy_fromio() and cx18_memset_io() is to increment by bytes, so use u8 pointers instead. Signed-off-by:

cx18: Throttle mmio to/from the CX23418 so boards work in older systems. The CX23418 couldn't reliably handle mmio at the rate at which the cx18 driver was attempting to access the chip. The PCI bridge arrangements and settings on modern motherboards still allowed the CX23418 to work OK, but it didn't work well on many older motherboards: mysterious I2C errors, firmware loading errors, etc. This patch adds a throttle to *all* mmio access to the CX23418. It defaults to a delay of 31 ns, but is adjustable by the mmio_ndelay module parm. My HVR-1600 and Raptor PAL/SECAM card now function for analog capture on a motherboard with an Intel 82810E Northbridge and 82801AA Southbridge. Signed-off-by:

cx18: Create cx18_ specific wrappers for all pci mmio accessesors. This is a first step in instrumenting all CX23418 PCI bus IO, to debug problems with accessing the CX23418's PCI memory mapped IO. Signed-off-by:

cx18: Correct CX23418 PCI configuration settings. The CX23418 doesn't have I/O space registers, so there was no need to try and turn them on (the card ignores the attempt to set the bit anyway). Also removed incorrect config space register setting that was errantly borrowed from ivtv. Signed-off-by:

Fix sparse warnings. None are serious, but cutting down on these helps find future serious sparse warnings/errors. Redid the av7710.c patch based on a suggestion by Oliver Endriss. Signed-off-by:

Disable "virtual" IR receiver on for 24xxx devices that have an internal IR blaster. In that case there's another another IR receiver present and to leave the virtual receiver available just causes confusion. This means that 24xxx users will no longer see a phantom IR chip. Signed-off-by:

This builds upon the previous pvrusb2 change to more formally implement full cropping support. This enables access from the driver's V4L interface, and enables access to full capabilities from sysfs as well. Note that this is only effective when in analog mode. It also will only work when the underlying digitizer's driver (saa7115 or cx25840 depending on the hardware) also implements the appropriate functions. Signed-off-by:

The pvrusb2 control mechanism up until now has used a constant int to hold a control's default value. This change makes it possible to retrieve the control's default through some other means, e.g. as a result of a query from lower level software. Signed-off-by:

The driver includes an internal table specifying additional information on a per device-type basis. This works great until somebody tries to run-time associate another USB ID with the driver. This change should hopefully allow the driver to fail gracefully under such a circumstance. Signed-off-by:

The earlier change from Hans Verkuil that pushed the BKL from video_open() down into the drivers should be unneeded for the pvrusb2 driver. This driver's implementation for open already protects its internal structures through other means, thus the BKL is not required. This change reverses Hans' previous change, for the pvrusb2 driver. It probably would have been a good idea for Hans to previously have asked for my ack before committing his change. Signed-off-by:

Add support for the 'full-ts' hardware modification. On full-featured cards the data throughput is limited by the hardware design. The full-ts mod removes this bottleneck, i.e. the card is able to deliver the complete transport stream of a transponder.

When the input is set to tuner and no antenna is connected, the BT848 can flood VPRES interrupts. So we don't want to enable this type of interrupts when the input it set to tuner. As we don't do anything when receiving such an interrupt anyway, the easiest fix is to simply not unmask this specific interrupt. Signed-off-by:

Replace the old register_chrdev with the more flexible register_chrdev_region. Ensure that the release() is called when the very last chardev usage was released, and not when the sysfs devices were removed. This should simplify hotpluggable drivers considerably. Tested-by:

Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches. Signed-off-by:

This patch is on behalf of Stephen Backway <stev391@email.com>, and represents two patches I received (and some subsequent whitespace cleanup I had due to how I pulled the patches). From the original author: a) Add DVB support for the Leadtek Winfast PxDVR3200 H. b) The tuner callback previously checked the command 3 times: 1) To see if it was the XC2028_RESET_CLK 2) To see if it was not the XC2028_RESET_TUNER 3) To see if it was the XC2028_RESET_TUNER This patch removes the third check.

A simple state machine was added to saa7134_ts. It has three states: SAA7134_TS_STOPPED SAA7134_TS_BUFF_DONE SAA7134_TS_STARTED When buffer_setup is run we start the TS initialization: set SAA7134_TS_STOPPED. When all buffers are prepared we write data into DMA register and set SAA7134_TS_BUFF_DONE. When the first buffer is active start TS and set SAA7134_TS_STARTED. When ts_release is called stop TS and set SAA7134_TS_STOPPED. Signed-off-by:Beholder Intl. Ltd. Dmitry Belimov <d.belimov@gmail.com> Signed-off-by:
